本发明提供一种曲面屏贴合装置,用于实现柔性显示层与曲面盖板相贴合,包括:基台,所述基台上表面形成有弧面,所述弧面为凹面,所述弧面的曲率与所述曲面盖板相吻合,用于适配固定所述曲面盖板;磁层,贴合于所述弧面底部的全部区域,用以使所述弧面产生磁场吸附力;所述磁层包括若干相互独立的条型磁场发生器,各所述条型磁场发生器相互平行,且所述条型磁场发生器沿所述弧面的曲边走向紧密排列;贴附辊轴,吸附于所述弧面上移动,用于对所述柔性显示层进行滚压成型;控制器,用于控制各所述条型磁场发生器沿所述弧面的弯曲方向依次开启,在开启任一所述条型磁场发生器的同时关闭前一个所述条型磁场发生器,用以形成移动磁场以引导所述贴附辊轴移动。The present invention provides a curved screen bonding device for implementing a flexible display layer and a curved cover plate, comprising: a base, the upper surface of the base is formed with a curved surface, and the curved surface is a concave surface, The curvature of the curved surface is matched with the curved cover plate for fitting and fixing the curved cover plate; the magnetic layer is attached to all the regions at the bottom of the curved surface for generating magnetic field adsorption force on the curved surface The magnetic layer includes a plurality of mutually independent strip-type magnetic field generators, each of the strip-type magnetic field generators being parallel to each other, and the strip-type magnetic field generators are closely arranged along the curved side of the curved surface; a shaft, adsorbed on the curved surface for rolling forming the flexible display layer, and a controller for controlling each of the strip-type magnetic field generators to be sequentially opened along a bending direction of the curved surface, The strip-type magnetic field generator is turned off while turning on any of the strip-type magnetic field generators to form a moving magnetic field to guide the attachment roller shaft to move.
所述条型磁场发生器开启之后即产生磁力,对位于其上部的贴附辊轴具有磁性吸附的作用,所述贴附辊轴压置于所述柔性显示层的上表面,所述贴附辊轴依借自身的重量以及受所述条型磁场发生器的磁吸力的作用,滚压所述柔性显示层将其贴合在所述曲面玻璃盖板的表面,所述贴附辊轴所经过的区域即完成贴合;由于所述弧面底部的全部区域均设置有所述条型磁场发生器,因此可实现所述贴附辊轴能够移动到所述弧面的全部区域,不受曲面屏设计曲率的影响。After the strip type magnetic field generator is turned on, a magnetic force is generated, and the attaching roller shaft located at the upper portion thereof has a magnetic attraction effect, and the attaching roller shaft is pressed against the upper surface of the flexible display layer, and the attaching The roller shaft is pressed against the surface of the curved glass cover plate by the weight of the roller and by the magnetic attraction force of the strip-type magnetic field generator, and the roller shaft is attached The passing area completes the fitting; since the strip-shaped magnetic field generator is disposed in all the areas of the bottom of the curved surface, the attached roller shaft can be moved to the entire area of the curved surface, and is not The effect of the curvature of the curved screen design.
如图2所示,本发明的曲面屏贴合装置,包括基台201,所述基台201的上表面形成有内凹的弧面202,所述弧面202的底面紧密排列有若干条型磁场发生器203,所述条型磁场发生器203相互平行设置,且沿所述弧面202的曲边走向分布,以形成所述贴附辊轴204的移动轨道;所述弧面上配合固定好已形成曲面的曲面玻璃盖板205,所述曲面玻璃盖板205上放置预贴合的柔性显示层206。As shown in FIG. 2, the curved screen bonding apparatus of the present invention comprises a base 201. The upper surface of the base 201 is formed with a concave curved surface 202. The bottom surface of the curved surface 202 is closely arranged with a plurality of strips. The magnetic field generator 203 is disposed in parallel with each other and distributed along the curved side of the curved surface 202 to form a moving track of the attaching roller shaft 204; the arc surface is fixedly fixed A curved glass cover 205 having a curved surface is formed, and a pre-applied flexible display layer 206 is placed on the curved glass cover 205.
具有较大曲率的面板,通常最大曲率部分位于面板的两端,位于面板中间的部分较为平坦,所述贴附辊轴204在从平坦区域移动至大曲率的区域时,处于爬升的阶段,受所述贴附辊轴204自身重力以及其圆滑表面的影响,爬升较为吃力,通过改变所述条型磁场发生器203的结构可解决该缺陷。A panel having a large curvature, usually the maximum curvature portion is located at both ends of the panel, and the portion located in the middle of the panel is relatively flat, and the attachment roller shaft 204 is in a climbing stage when moving from a flat region to a region of large curvature. The self-gravity of the attaching roller shaft 204 and its smooth surface are relatively difficult to climb, and the defect can be solved by changing the structure of the strip-type magnetic field generator 203.
例如,位于所述弧面202的曲率较大区域的单个所述条型磁场发生器203,将其宽度设置为小于位于所述弧面202的小曲率区域的单个所述条型磁场发生器203的宽度;通过减小所述条型磁场发生器203的宽度,从而增大位于所述弧面202的曲率较大区域的条型磁场发生器203的密度,使得所述贴附辊轴204在相同的行程距离中,位于所述弧面202的大曲率区域的磁场分布密度,大于位于所述弧面202的小曲率区域的磁场分布密度,从而,在相邻的条型磁场发生器203切换时尽量避免对所述贴附辊轴204吸附力的衰减。For example, a single strip-type magnetic field generator 203 located in a region of curvature of the curved surface 202 has a width set to be smaller than a single strip-type magnetic field generator 203 located in a small curvature region of the curved surface 202. Width; by reducing the width of the strip-type magnetic field generator 203, thereby increasing the density of the strip-type magnetic field generator 203 located in a region of curvature of the curved surface 202 such that the attaching roller shaft 204 is In the same stroke distance, the magnetic field distribution density in the large curvature region of the curved surface 202 is greater than the magnetic field distribution density in the small curvature region of the curved surface 202, thereby switching between adjacent strip-type magnetic field generators 203 The attenuation of the adsorption force of the attaching roller shaft 204 is avoided as much as possible.
又如,位于所述弧面202的曲率较大区域的单个所述条型磁场发生器203通入的电流,大于位于所述弧面202的小曲率区域的单个所述条型磁场发生器203通入的电流;将位于曲率较大区域的单个所述条型磁场发生器203介入较大电流,以增强所述条型磁场发生器203对所述贴附辊轴204的吸附作用力,从而增强所述贴附辊轴204的爬升能力。For another example, a single strip-type magnetic field generator 203 located in a region of curvature of the curved surface 202 has a larger current than a single strip-type magnetic field generator 203 located in a small curvature region of the curved surface 202. a current flowing in; a single strip-type magnetic field generator 203 located in a region of curvature is interposed with a large current to enhance the adsorption force of the strip-type magnetic field generator 203 on the attaching roller shaft 204, thereby The climbing ability of the attaching roller shaft 204 is enhanced.
通过改变所述贴附辊轴204的结构也可解决上述缺陷;例如,所述贴附辊轴204选择为多棱柱,所述贴附辊轴204的端面形状为多边形,所述贴附辊轴204与所述柔性显示层206相接触的表面由多个平面相接形成,与圆柱形的贴附辊轴204相比,单独一平面中的各个区域,与单个所述条型磁场发生器203之间的距离相同,而弧面202中的各个区域,与单个所述条型磁场发生器203之间的距离由中间区域向两侧区域递增,相对而言,棱柱形的贴附辊轴204在同一位置所接收到的吸附力较多,因此吸附能力更强,有助于提升所述贴附辊轴204在较大曲率区域的爬升能力。The above defects can also be solved by changing the structure of the attaching roller shaft 204; for example, the attaching roller shaft 204 is selected as a polygonal prism, and the end surface shape of the attaching roller shaft 204 is a polygonal shape, and the attaching roller shaft The surface of the 204 that is in contact with the flexible display layer 206 is formed by a plurality of planes in contact with each other in a single plane compared to the cylindrical attachment roller shaft 204, and a single strip-type magnetic field generator 203 The distance between the same is the same, and the distance between each of the curved faces 202 and the single strip-type magnetic field generator 203 is increased from the intermediate portion to the both sides, and the prismatic applicator roller 204 is relatively The suction force received at the same position is large, so the adsorption capacity is stronger, which helps to improve the climbing ability of the attachment roller shaft 204 in a region of large curvature.
优选的,棱柱形的所述贴附辊轴204,相邻两个平面之间的连接部由曲面连接,换言之,所述贴附辊轴204端面的多边形,相邻两条边之间由曲线连接;从而,在增强所述贴附辊轴204吸附能力的同时,便于所述贴附辊轴204滚动,提高贴合效率。Preferably, the prismatic attachment roller shaft 204 has a connecting portion between two adjacent planes connected by a curved surface, in other words, a polygon of the end surface of the attachment roller shaft 204, and a curve between adjacent two sides Thereby, while the adsorption capacity of the attachment roller shaft 204 is enhanced, the attachment roller shaft 204 is facilitated to roll, and the fitting efficiency is improved.
所述贴附辊轴204在移动的过程中,可能存在倾斜状况,所述贴附辊轴204稍微倾斜,继续移动后将会将斜角放大,导致所述贴附辊轴204无法顺利到达曲面的端点,同时使得所述贴附辊轴204的移动轨迹不能覆盖全部的所述柔性显示层206,将会影响柔性显示层206的贴合质量,通过改变所述贴附辊轴204的结构可解决该缺陷。During the movement of the attaching roller shaft 204, there may be a tilting condition, the attaching roller shaft 204 is slightly inclined, and the oblique angle will be enlarged after continuing to move, so that the attaching roller shaft 204 cannot smoothly reach the curved surface. The end point of the film, while the moving track of the attaching roller shaft 204 cannot cover all of the flexible display layer 206, will affect the bonding quality of the flexible display layer 206, by changing the structure of the attaching roller shaft 204. Solve the defect.
例如,使所述贴附辊轴204的长度大于或等于所述基台201的最小宽度,从而,所述贴附辊轴204在移动过程中存在的微型倾斜不会影响贴合质量。For example, the length of the attachment roller shaft 204 is made greater than or equal to the minimum width of the base 201, so that the micro-tilt that the attachment roller shaft 204 exists during the movement does not affect the quality of the attachment.
又如,在所述贴附辊轴204的两端设置有限位挡片,所述限位挡片的边缘超出所述贴附辊轴204的外侧,例如,所述限位挡片为圆形片,所述限位挡片的圆心与所述贴附辊轴204端面的圆心相重合,所述限位挡片的直径大于所述辊轴端面的直径;又如,所述限位挡片为多个,多个所述限位挡片间隔设置于所述贴附辊轴204端部的外侧。For example, a limit stop is disposed at both ends of the attaching roller shaft 204, and an edge of the limiting stopper is outside the outer side of the attaching roller shaft 204. For example, the limiting stopper is circular. a center of the limit stop of the attachment roller 204 coincides with a center of an end surface of the attachment roller shaft 204, the limit stopper has a diameter larger than a diameter of the end surface of the roller shaft; for example, the limit stopper A plurality of the limit stoppers are spaced apart from the outer side of the end of the attachment roller shaft 204.
所述贴附辊轴204在移动的过程中,所述限位挡片将所述贴附辊轴204限制在所述基台201上,只能朝向所述曲面的弯曲方向移动,使所述限位挡片与所述条型磁场发生器203保持平行状态,从而避免所述贴附辊轴204偏移磁场。During the movement of the attaching roller shaft 204, the limiting stopper restricts the attaching roller shaft 204 to the base 201, and can only move toward the bending direction of the curved surface, so that the The limit stop is kept in parallel with the strip type magnetic field generator 203, thereby preventing the attaching roller shaft 204 from shifting the magnetic field.
所述贴附辊轴204为铁质辊轴,所述贴附辊轴204表面粘覆有硅胶层,所述硅胶层有助于增大所述贴附辊轴204与所接触面的摩擦力,进而具有更好爬升能力。The attaching roller shaft 204 is an iron roller shaft, and the surface of the attaching roller shaft 204 is adhered with a silica gel layer, and the silica gel layer helps to increase the friction between the attaching roller shaft 204 and the contact surface. And thus have a better climbing ability.
